Baxter has made a pitstop at Iowa 80 before picking up a 116ft-long wind turbine blade that he’s driving down to Texas, 900 miles away.

Baxter, 48, is one of the 1.8 million Americans, mainly men, who drive heavy trucks for a living, the single most common job in many US states. Driving is one of the biggest occupations in the world. Another 1.7 million people drive taxis, buses and delivery vehicles in the US alone. But for how long? Having “disrupted” industries including manufacturing, music, journalism and retail, Silicon Valley has its eyes on trucking.

Google, Uber, Tesla and the major truck manufacturers are looking to a future in which people like Baxter will be replaced – or at the very least downgraded to co-pilots – by automated vehicles that will save billions but will cost millions of jobs. It will be one of the biggest changes to the jobs market since the invention of the automated loom – challenging the livelihoods of millions across the world.

Finn Murphy, author of The Long Haul, the story of his life as a long-distance truck driver, says the days of the truck driver as we know him are coming to an end. Trucking is a $700bn industry, in which a third of costs go to compensating drivers, and, he says, if the tech firms can grab a slice of that, they will.
